OPIC dioes not help out the relentlessly taxed and regulated rather it is a subsidy for the nations that recieve the corporate investment. It was originally formed as part of the foreign aid bill (under Richard M. Nixon). It still is considered a form of foreign aid. it is aid of which the People's Republic od China is a recipient.
Now the corporations being somewhat rational are not going to invest in a higher risk investment without either risk mitigation or a vastly higher rate of return. Thus OPIC with the insurance it provides mitigates the risk. The corporation could make money no matter where they invested. The rate of return would be different based upon location but in the final analysis it would be balnced by risk.
You are the one advocating continued taxpayer support for the outflow of investment capital. You are the one arguing for MARXIST intervention. You are the one arguing for an internationalist viewpoint.
